In this study, ZnO nanoparticles made by hydrothermal method for adsorption of phosphate from waterThe adsorption of phosphate on ZnO nanomaterials follows the isothermal adsorption modelsLangmuir, Tempkin and Freundlich, single-layer adsorption, in the condition of heterogeneousmaterial surface, there is weak interaction between adsorbent and adsorbents. According to theisothermal adsorption model, Langmuir has determined the maximum adsorption capacity of 769.23(mg g). Phosphate adsorption of ZnO nanomaterials follows Lagergren's apparent second-order kineticmodel, spontaneous and exothermic.Keywords: Nanoparticles ZnO, equilibrium, kinetic and thermodynamic, phosphate, Aqueous solution.
